EGIT branch checkout errors

EGIT branch checkout errors

[Chris Dumoulin]

Using EGIT in Eclipse, I'm able to create a new branch, but not able to 
checkout a branch. When I try Team->Branch...->Checkout, nothing 
happens, so I launched Eclipse from a terminal to see any output it 
might be giving. Here's what I got:

Something is wrong in the WorkDirCheckout class. Could you send these
things

git ls-tree -r HEAD
git-ls-tree -r branch-you-try-to-switch-to
git diff --name-only

Then post it to http://code.google.com/p/egit/issues/list
